I am having problems with a chat programme and was told that it may be because my dedicated server is using vhosts.

My dedicated server is duel xeon and is a deciated box.

I would have thought all deciated servers used vhosts other wise you would only ever have one domain on your box.

Are there other alternatives to vhosts in dedicated servers , if so what are they ?

If someone can explain this I would realley appreciate it.
